BISMARCK, ND — A man who used to own McDonald's restaurants in North Dakota is about $10,000 richer after selling a 20-year-old container of McJordan barbecue sauce to a buyer in Chicago.

The sauce was used on McJordan Burgers, named for basketball icon Michael Jordan. The promotional item was sold in limited markets for a short time in the 1990s, when Jordan led the Chicago Bulls to six NBA championships.

Mort Bank, of Bismarck, saved the gallon jug of sauce after selling his McDonald's restaurants in Bismarck-Mandan and Minot in 1996.

Bank told the Chicago Tribune that the buyer was not Jordan himself. Jordan opened a steakhouse in Chicago last year.

"I'm sure he's a Bulls or Michael Jordan fan, and hopefully he's not going to put it on his ribs or his burger," Bank told KXMB-TV of the buyer. "But it's up to him; he can do whatever he wants with it."

Bank said he has at least three storage units full of McDonald's memorabilia and other collector's items that he has been selling on eBay for three years. He has sold items to buyers as far away as China, Japan, Brazil and Europe, though never for as much money as the sauce garnered.

"I'm pretty ecstatic," he told the Bismarck Tribune. "You never know what is going to be a hot item."
